If you take your news in podcast format, you can find John Resig taking about the 1.4 release and the future of jQuery on the official jQuery podcast episode 7. On this episode John also announced the jQuery team will be focusing on testing and optimizing for mobile devices. This could mean a version that addresses the 25k caching limit and other jQuery performance issues found on the iPhone.

Google has already pushed version 1.4 out on it’s CDN, please reference this link for the details.
